ml STAR/2.6.0c-foss-2016b STAR Usage: STAR [options]... --genomeDir REFERENCE --readFilesIn R1.fq R2.fq Spliced Transcripts Alignment to a Reference (c) Alexander Dobin, 2009-2015 ### versions versionSTAR 020201 int>0: STAR release numeric ID. Please do not change this value! versionGenome 020101 020200 int>0: oldest value of the Genome version compatible with this STAR release. Please do not change this value! ### Parameter Files parametersFiles - string: name of a user-defined parameters file, "-": none. Can only be defined on the command line. ### System sysShell - string: path to the shell binary, preferably bash, e.g. /bin/bash. - ... the default shell is executed, typically /bin/sh. This was reported to fail on some Ubuntu systems - then you need to specify path to bash. ### Run Parameters runMode alignReads string: type of the run. alignReads ... map reads genomeGenerate ... generate genome files inputAlignmentsFromBAM ... input alignments from BAM. Presently only works with --outWigType and --bamRemoveDuplicates. liftOver ... lift-over of GTF files (--sjdbGTFfile) between genome assemblies using chain file(s) from --genomeChainFiles. runThreadN 1 int: number of threads to run STAR runDirPerm User_RWX string: permissions for the directories created at the run-time. User_RWX ... user-read/write/execute All_RWX ... all-read/write/execute (same as chmod 777) runRNGseed 777 int: random number generator seed. ### Genome Parameters genomeDir ./GenomeDir/ string: path to the directory where genome files are stored (for --runMode alignReads) or will be generated (for --runMode generateGenome) genomeLoad NoSharedMemory string: mode of shared memory usage for the genome files. Only used with --runMode alignReads. LoadAndKeep ... load genome into shared and keep it in memory after run LoadAndRemove ... load genome into shared but remove it after run LoadAndExit ... load genome into shared memory and exit, keeping the genome in memory for future runs Remove ... do not map anything, just remove loaded genome from memory NoSharedMemory ... do not use shared memory, each job will have its own private copy of the genome genomeFastaFiles - string(s): path(s) to the fasta files with the genome sequences, separated by spaces. These files should be plain text FASTA files, they *cannot* be zipped. Required for the genome generation (--runMode genomeGenerate). Can also be used in the mapping (--runMode alignReads) to add extra (new) sequences to the genome (e.g. spike-ins). genomeChainFiles - string: chain files for genomic liftover. Only used with --runMode liftOver . genomeFileSizes 0 uint(s)>0: genome files exact sizes in bytes. Typically, this should not be defined by the user. genomeConsensusFile - string: VCF file with consensus SNPs (i.e. alternative allele is the major (AF>0.5) allele) ### Genome Indexing Parameters - only used with --runMode genomeGenerate genomeChrBinNbits 18 int: =log2(chrBin), where chrBin is the size of the bins for genome storage: each chromosome will occupy an integer number of bins. For a genome with large number of contigs, it is recommended to scale this parameter as min(18, log2[max(GenomeLength/NumberOfReferences,ReadLength)]). genomeSAindexNbases 14 int: length (bases) of the SA pre-indexing string. Typically between 10 and 15. Longer strings will use much more memory, but allow faster searches. For small genomes, the parameter --genomeSAindexNbases must be scaled down to min(14, log2(GenomeLength)/2 - 1). genomeSAsparseD 1 int>0: suffux array sparsity, i.e. distance between indices: use bigger numbers to decrease needed RAM at the cost of mapping speed reduction genomeSuffixLengthMax -1 int: maximum length of the suffixes, has to be longer than read length. -1 = infinite. ### Splice Junctions Database sjdbFileChrStartEnd - string(s): path to the files with genomic coordinates (chr <tab> start <tab> end <tab> strand) for the splice junction introns.
